Abstract
The utility model discloses a rock bore type anchor structure, which can effectively reduce the construction amount and the construction cycle so as to lower the engineering cost. The rock bore type anchor structure comprises a rock bore (10), an anchor cable (11), an outer anchoring part (20) and an inner anchoring part (30). The rock bore (10) extends into the rock and soil bearing layer inwardly from the outside of the layer. The outer anchoring part (20) and the inner anchoring part (30) are respectively fixed to the outer end and the inner end of the rock bore (10). The anchor cable (11) passes through the rock bore (10). The two ends of the anchor cable (11) are in anchoring connection with the outer anchoring part (20) and the inner anchoring part (30) respectively through an outer anchoring member (21) and an inner anchoring member (31). Due to the adoption of the rock bore type anchor structure, the construction amount and the construction cycle are effectively reduced and the building material is saved so as to lower the engineering cost. The anchor cable is easy to replace and maintain. The rock bore type anchor structure is wide in application range and is suitable for various civil engineering in need of the drawing resistance. The rock bore type anchor structure has better social and economic benefits.
Description
Technical field
The utility model relates to the anchorage that uses in the civil engineering, the anchorage of particularly building in the fragmented rock body or the soil body.
Background technology
At present in the clay model engineering to needing the engineering of huge tension pull out force in fragmented rock body or the soil body environment, often to build gravity anchor separately.Present gravity anchor adopts concrete pouring to form the anchorage of big volume usually, provides engineering required tension pull out force through its substrate frictional resistance.Because traditional gravity anchor bulky often causes constructional difficulties when in the civil engineering that build in the mountain area, using, and is unfavorable for reducing construction costs.
The utility model content
The utility model technical problem to be solved provides a kind of petrosal foramen formula anchorage structure, can reduce construction volume and construction period effectively, and help reducing construction costs.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The petrosal foramen formula anchorage structure of the utility model, it is characterized in that: it comprises petrosal foramen, anchor cable, outer anchorage element and interior anchorage element; The petrosal foramen ecto-entad extends in the geotechnical body bearing stratum, and outer anchorage element, interior anchorage element are fixedly installed on outer end, the inner of petrosal foramen respectively; Anchor cable passes petrosal foramen, and its two ends form anchor connection through outer ground tackle, interior ground tackle with outer anchorage element, interior anchorage element respectively.
The beneficial effect of the utility model is, can effectively reduce construction volume and construction period, saves constructional materials, helps reducing construction costs; Its anchor cable is easy to change, safeguard; Wide application is applicable to the various civil engineerings that need the drawing drag, has better society and economic benefit.
Description of drawings
This manual comprises like next width of cloth accompanying drawing:
Fig. 1 is the structural representation of the utility model petrosal foramen formula anchorage structure.
Component shown in the figure, toponym and pairing mark: petrosal foramen 10, anchor cable 11, outer anchorage element 20, outer ground tackle 21, interior anchorage element 30, interior ground tackle 31, service depot 32, passage 33.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1, the petrosal foramen formula anchorage of the utility model structure comprises petrosal foramen 10, anchor cable 11, outer anchorage element 20 and interior anchorage element 30.Petrosal foramen 10 ecto-entads extend in the geotechnical body bearing stratum, and outer anchorage element 20, interior anchorage element 30 are fixedly installed on outer end, the inner of petrosal foramen 10 respectively.Anchor cable 11 passes petrosal foramen 10; Its two ends are respectively through outer ground tackle 21, interior ground tackle 31 and outer anchorage element 20, the 30 formation anchor connections of interior anchorage element; Make geotechnical body and outer anchorage element 20, interior anchorage element 30 be combined to form a common stressed integral body, this stressed integral body becomes an anchorage that the tension pull out force can externally be provided.Said outer anchorage element 20, interior anchorage element 30 adopt reinforced concrete members usually.Compare with traditional gravity anchor, the utility model can effectively reduce construction volume and construction period, saves constructional materials, helps reducing construction costs, and its anchor cable is easy to change, safeguard.
With reference to Fig. 1, the construction sequence of the utility model is: in excavation passage 33 to the geotechnical body bearing stratum, and excavate out service depot 32; Drilling petrosal foramen 10; Outside geotechnical body with service depot 32 in build respectively steel concrete form outside anchorage element 20, interior anchorage element 30; Lay anchor cable 11, and make anchor cable 11 and outer anchorage element 20, the 30 formation anchor connections of interior anchorage element through outer ground tackle 21, interior ground tackle 31; Backfilling working chamber 32, passage 33.
Some principles of the above the utility model petrosal foramen formula anchorage structure that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
